ELEVATION: BTL. 10,300-9,300
ASPECT: N, SE. All slope angles under 35 degrees.
WEATHER: A couple light wind gusts. Otherwise clear sky, strong solar and warm temps.
Surface crusts where about 10″ this morning over wet grains to the ground. These crusts where skiing well on SE aspects at this elevation around 11am. During the noon to 1pm range these crusts where breaking down on SE aspects and becoming unsupportive to boots or skis. During this timeframe we were seeing and hearing huge rumbling collapses on these aspects.
After 1pm we skied on a north aspect that was supportive to both ski and boots with good skiing. This aspect still produced very large rumbling collapses while traveling on it.
